Nudging has received ample attention in scientific literature as an environmental strategy to promote healthy diets, and may be effective for reaching populations with low socioeconomic position (SEP). Therefore, the objective of this study was to investigate how the determinants of food choice shape the perceptions regarding supermarket-based nudging strategies among adults with low SEP. We conducted semi-structured interviews among fifteen adults with low SEP using a pre-defined topic list and visual examples of nudges. Interviews were recorded and transcribed verbatim and content analysis was used to analyse the data. The results show that food costs, convenience, healthiness, taste, and habits were frequently mentioned as determinants of food choice. However, the relative importance of these determinants seemed to be context-dependent. Interviewees generally had a positive attitude towards nudges, especially when they were aligned with product preferences, information needs, and beliefs about the food environment. Still, some interviewees also expressed distrust towards nudging strategies, suspecting ulterior motives. We conclude that nudging strategies should target foods which align with product preferences and information needs. However, the suspicion of ulterior motives highlights an important concern which should be considered when implementing supermarket-based nudging strategies.
助推在科学文献中受到了广泛关注，被认为是促进健康饮食的一种环境策略，对于处于低社会经济地位（SEP）的人群可能是有效的。因此，本研究的目的是调查食品选择的决定因素如何影响处于低 SEP 的成年人对基于超市的助推策略的看法。我们使用预先确定的主题列表和助推示例对 15 名处于低 SEP 的成年人进行了半结构化访谈。访谈被录音并逐字转录，内容分析用于分析数据。结果表明，食品成本、便利性、健康、口味和习惯经常被提及为食品选择的决定因素。然而，这些决定因素的相对重要性似乎取决于具体情况。受访者普遍对助推持积极态度，尤其是当它们与产品偏好、信息需求和对食品环境的信念一致时。然而，一些受访者也对助推策略表示不信任，怀疑有不可告人的动机。我们的结论是，助推策略应该针对与产品偏好和信息需求一致的食品。然而，对不可告人动机的怀疑突显了在实施基于超市的助推策略时应考虑的一个重要问题。
